I have a tropaeolum brachyceras tuber that i planted in a container in April, there are no signs of growth yet, when would you expect to see some growth and when would flowering occur.I planted it at least six inches deep as according to internet advice they like being planted quite deep.

I don't know this plant, but the site I looked at said it came from Chile and likes the following:
"Watering conditions:
Dry, arid areas, with long drought periods of 6 - 10 months. Precipitations of 100 mm - 300 mm. are concentrated in winter.
Somewhat dry areas where the drought may last 3 - 5 months. Precipitations of 400 - 800 mm. are concentrated in winter.

Light conditions:
Fully exposed to the sun. Level areas or slopes facing north.
Some shadow. Some protection against direct sunlight, some shadow from vegetation, filtering about 20 - 40 % of light."

As it comes from a very arid region, I'd be careful not to overwater the tuber as it may rot. Several people talk about them sprouting in dry soil. I'd guess as a drought region plant the tuber may take a little while to come back to life. You can also get seed but have to wait for the second year before it flowers.

Please post if you succeed. Where did you buy the tuber of this unusual plant?
